I'm not sure why you expect LC_CTYPE to set the user locale. LC_CTYPE
defines the locale used for character conversions, and that's what
Wine does by setting the system locale. The user locale affects things
like resource loading and date formats, but these have nothing to do
with LC_CTYPE.

If the system locale is set to Russian, then I'd expect Russian
characters to display properly no matter what the user locale is set
to. It sounds like there's a real bug here, and playing with the
locale setting is only hiding it.
